Abstract
A safety system (10) for shutting down a nuclear reactor under overload conditions is provided using a series of parallel-connected computing modules (14a, 14b, 14c, 14d, 14e) each of which receives data on a particular reactor parameter (P, T, .phi..sub.T, .phi..sub.B, W) and each of which produces a function [f(P), f(T), f(.phi..sub.T), f(.phi..sub.B), f(W)] indicating the percentage of maximum reactor load that the parameter (P, T, .phi..sub.T, .phi..sub.B, W) contributes. The various functions [f(P), f(T), f(.phi..sub.T), f(.phi..sub.B), f(W)] are added together to provide a control signal (S) used to shut down the reactor under overload conditions.
Claims6
A safety system for a nuclear reactor comprising:
- a series of transducers for measuring various different parameters of the nuclear reactor's operation;
- a series of parallel-connected computing stations each individually connected to each of the transducers measuring one different parameter of the nuclear reactor's operation with each computing station calculating a function of that particular parameter connected thereto indicative of percentage of maximum reactor load contributed by that parameter;
- a summing station for receiving all of the functional outputs of all the respective computing stations and summing them up to establish a control signal indicative of maximum percentage of full power reactor operation.
